Claims. l n This invention relates to a cooking stove, and particularly to its construction for permitting convenient viewing of the interior of the oven.

It is recognized that various structures `have heretofore been employed for permitting observation of the oven contents during baking without opening the oven door. This has been accomplished principally by providing a window in the oven door which has proven unsatisfactory and to a large extent has been abandoned in thet stove industry for the reason, among others, that the glass of the window becomes browned and unsightly. Various periscope arrangements have also been attempted, but without success.

It is therefore the purpose of this invention to provide an observation window for the oven contents which will not detract from the appearance of the stove, and particularly will permit of convenient viewing by looking down through the cooking top. Thus, the contents may be observed by looking down through the top of the stove instead of bending down to a position required for looking through an oven door, as heretofore.

The invention therefore contemplates forming the top lining of the oven with an upwardly recessed dome-like portion terminating in an aperture carrying a glass panel adjacent the cooking top of the stove and providing a clamping and sealing structure for securing such panel in place as a section of the top of the oven While permitting of its ready removal to prevent it becoming browned and somewhat opaque over a period of use. A relatively smaller window supported by a removable frame is mounted flush with the cooking top of the stove in substantially spaced relationlto the glass panel so that when standing over the stove one may look down through the window and panel into the interior of the oven. n

The full nature of the invention will be understood from the accompanying drawings and the following description and claims:

Fig. 1 is a perspective view of a stove showing the relative positions of the oven viewing window and oven compartment.

Fig. 2 is a longitudinal section through the ovenviewing structure and the upper portion of the oven.

Fig. 3 is a transverse section through the upper portion of the stove taken centrally of the oven with the lower and rear portions thereof broken away.

In the drawings there is shown a cooking stove l0 having an oven door Il and a cooking top l2 with the usual burners I3. Within the stove, centrally thereof as herein shown, fcrclosure by the oven door ll there is an oven compartment I4 having an end wall lining l and a top lining lr6. The oven door is provided with a handle l1 and the front panel of the stove with a switch button i3 for convenient control oi' an electric light bulb I9 within the oven compartment. Mounted transversely of the oven compartment and secured to the inner side of the front panel of the stove there is provided the usual sheet metal flange 2l) dependent into position for sealing engagement by the upper edge of the oven door. The above described structure is of the usual character generally found in stoves of this type.

The top lining it instead of being carried straight across the top of the oven, as indicated by the dotted line A in Fig. 3, is formed with an upwardly sloping wall 2| terminating in a horizontal portion 22 in which a viewing aperture 23 is provided. Said aperture is provided at the upper forward portion of the oven compartment lying adjacent the front panel of the cooking top i2and is closed by a glass panel 24. Said glass panel, together with the wall 2l and its horizontal portion 22, comprises a part of the top lining of the oven of recessed or domelike form.

The portion 22 of the lining terminates in an upwardly-extending and inwardly-flanged frame section 25, the flange thereof forming a seat for supporting the glass panel. The glass panel is removably secured in its seating position on said frame section 25 by a frame member 26. Said frame member is formed with an upstanding wall sloping inwardly, as indicated at 2l, against which the forward and end edges of the glass panel frictionally engage and become wedged after inserting the rear edge of the panel under a clip-like formed portion of said member, as indicated at 28. It will be observed that the frame member 26 is generally in the form of a spring metal band having its walls flared upwardly and outwardly and conned within the wall section 29 of the recessed opening in the top lining I6. The lower portion of one side of the wall, preferably toward the front of the stove, has its lower edge sloping inwardly, as indicated at 21. The opposite wall, toward the rear of the stove, is formed to slope downwardly and rearwardly, terminating in the cliplike spring formation at 28 spaced forwardly from the wall section 29 for providing a spring shoulder under which the rear edge of the glass panel may be slipped and clamped, whereupon the opposite edge thereof may be wedged downwardly against the inwardly sloping portion of the wall at 21. Thus, the resilient frame member 26 is confined within the opening and is coextensive with the seating flange 25, and is positioned for engagement with the peripheral edges of the glass panel 2d for yieldingly engaging the upper peripheral portion of said panel and removably clamp it at 28 against the seating flange. By reason of this structure the glass panel 24 may conveniently be removably held in place by the clamping at 2S and wedging at 2l, and readily removed by slipping the forward edge of the panel upwardly at 2l against the spring tension of the clamp formation at 28 to permit it to slide therefrom.

Embracing the member 26 there is a wall section 29 of the stove sloping upwardly and forwardly thereof from the frame section 25 of the oven lining, said wall section terminating in an aperture adjacent and surrounding a window opening 3@ in the cooking top l2. The opening 313 is preferably elongated to extend the full length of the glass panel, as shown in Fig. 2, but is considerably narrower, as shown in Fig. 3. It carries a glass window 3| supported by a window frame 32. Said window frame is laterally flanged to seat within a depressed ledge 33 of the cooking top surrounding the opening 30. Said ledge is perforated at its end portions to receive locating and interlocking lugs 34 depending from the frame 32.

For cleaning purposes the window and its frame 32 may be lifted from the cooking top l2, whereupon by reaching into the oven and pushing up on the forward portion of the glass panel it may be slipped from its frictional engagement by the sloping wall of the frame member 26 upwardly until it may be grasped and slipped from its clamping engagement by the clip-like portion 28 thereof. Said glass panel may then be removed from the stove through the opening 3Q in the cooking top.

In use, with the glass panel and window in position, the oven may be readily and conveniently viewed by pressing the button i8 to illuminate the oven by the lamp E9 and then bending down one may observe the interior through the window 3l.
